Burning muscle is a common concern for people looking to lose weight and get in shape. When losing weight, it is normal to lose both fat and muscle, and losing weight too quickly can lead to greater muscle loss. The body's natural response is to burn sugar first, then glycogen, and finally, protein. Therefore, it is important to understand how to fuel your body properly before and after a workout to ensure you are burning fat and not muscle. A combination of strength training and cardio is critical for maintaining muscle mass and burning fat.

What You'll Learn
Losing weight too quickly can cause muscle loss
Losing weight too quickly can lead to muscle loss, also known as sarcopenia. This is because when you diet, you don't just lose fat—you lose muscle too. While it was previously believed that people with more body fat lost less muscle in a calorie deficit, this has been disproven. Both lean and obese people lose significant amounts of muscle when dieting, though ethnicity and genetics may play a role. For example, studies show that Black people tend to lose more muscle mass in a calorie deficit than white people.
To lose weight sustainably without losing muscle, it is recommended to lose about a pound a week, which is a deficit of around 200 to 500 calories a day, depending on your activity level. Losing weight rapidly is usually not sustainable and can lead to a significant loss of muscle mass. A decrease in calorie-burning muscle mass slows our metabolism, impacting our ability to maintain our weight in the long term.
To prevent muscle loss while losing weight, it is essential to combine exercise with a diet higher in protein. This is because exercise stimulates muscle growth, but this process requires an adequate supply of protein. Strength-building exercises, such as weightlifting, are critical to preventing muscle loss. Cardio exercises, on the other hand, can result in muscle loss if done excessively without sufficient protein intake.
Signs of muscle loss include sagging skin in the arms and legs and difficulty completing weight-based exercises that were previously manageable. As people age, the rate of muscle loss doubles, with people in their mid-30s to 40s losing about 5 to 10% of their muscle mass per decade. Therefore, it is important to incorporate strength-building exercises and sufficient protein intake into one's weight loss plan to maintain muscle mass.

Calorie deficit and cardio can lead to muscle loss
Calorie deficit and cardio can indeed lead to muscle loss, but this can be mitigated with the right approach. When aiming for weight loss, the goal is typically to lose fat while retaining or even gaining muscle. However, it is common to lose muscle instead of fat, and a calorie deficit combined with excessive cardio can contribute to this.
When you are in a calorie deficit, your body turns to its stored energy sources to fuel itself. Carbohydrates are the body's primary energy source, so it breaks down carbs and fats first. If your body doesn't have enough carbohydrates, it will start breaking down muscle tissue for energy, leading to muscle loss. This is more likely to occur if you are also engaging in high-intensity cardio workouts that burn a significant number of calories.
To prevent muscle loss, it is crucial to fuel your body adequately before and after workouts. Consuming high-protein foods is essential, as protein is one of the key macronutrients used for energy during exercise. Research suggests that a diet higher in protein can help prevent muscle loss during weight loss. Additionally, combining cardio with resistance or strength training can help preserve muscle mass. Resistance training has been shown to have a muscle-sparing effect, and when paired with adequate protein intake, it can effectively mitigate muscle loss.
It's important to note that the rate of weight loss should be gradual and sustainable. Losing weight too quickly can lead to a higher proportion of muscle loss. Aiming for a weight loss of about one pound per week is recommended, which translates to a calorie deficit of around 200 to 500 calories per day, depending on your activity level. Consulting with a registered dietitian or doctor can help you determine the right calorie deficit and protein intake for your individual needs.

Muscle loss signs: sagging skin, difficulty with weight exercises
Sagging skin and difficulty with weight exercises are two signs that you may be experiencing muscle loss.
Sagging skin is a common issue that can occur when losing weight. It is often associated with the loss of fat, and it can happen anywhere on the body, including the face and abdomen. The likelihood of sagging skin increases with age, as younger skin tends to bounce back more easily. Additionally, people who have lost a significant amount of weight, such as 100 pounds or more, are more prone to experiencing sagging skin. This can be due to the damage caused to collagen and elastin fibres in the skin during periods of carrying extra weight.
Difficulty with weight exercises can be another indicator of muscle loss. You may notice a decrease in your strength or the number of repetitions you are able to perform during weight training. This could be a sign that your body is burning muscle instead of fat during your workouts. To prevent muscle loss, it is important to ensure proper fuelling before and after your workouts, including consuming high-protein foods.
While cardio exercises are important for burning calories, focusing solely on cardio can contribute to muscle loss. A balanced approach that includes both cardio and strength training is recommended for maintaining muscle mass while losing weight. Strength training helps to build muscle mass and can be done through exercises such as push-ups, squats, and weight lifting. It is important to gradually increase the weight and intensity of strength training exercises to continue challenging your muscles and promoting growth.
Other signs of muscle loss include a decrease in body circumferences without a change in body fat percentage and a lack of shaping in the desired areas. Additionally, as you age, your rate of muscle loss increases, with individuals in their 60s and 70s experiencing double the rate of muscle loss compared to their 30s and 40s.

Strength training helps retain muscle
Strength training is an essential part of maintaining muscle mass. While it is natural to lose muscle mass as we age, strength training can slow down or even prevent this progression.
Strength training, also called resistance or weight training, brings many benefits. Firstly, it strengthens muscles, which can help us continue the activities we enjoy as we get older. Strength training does not necessarily result in larger muscles, but rather, it helps to maintain muscle mass and function, which is important for our quality of life.
Additionally, some types of strength training can improve bone health and reduce the risk of diabetes and related diseases. Research also suggests that strength training can positively impact our mental health. Studies have shown that strength training can reduce symptoms of post-traumatic stress disorder (PTSD) and may also help with anxiety and depression.
To maintain muscle mass, it is important to combine strength training with a balanced diet. A healthy caloric deficit, where you consume fewer calories than you burn, is important for weight loss. However, a severe calorie deficit, especially when combined with a low-protein diet, can result in muscle loss. Therefore, it is crucial to ensure adequate protein intake, as protein is essential for muscle growth and repair.
In addition to diet, both cardio and strength training are critical for maintaining muscle mass while losing weight. While cardio exercises burn more calories, strength training helps build and retain muscle. A balanced approach, including a variety of exercises and a healthy diet, is the key to preserving muscle mass while improving overall health and well-being.

High-protein diets may not prevent muscle loss
When trying to lose weight, it is common to lose muscle instead of fat. This can have repercussions on your fitness, strength, and metabolism. To lose weight, you need to be in a calorie deficit, which means consuming fewer calories than your body uses or exercising to burn more calories than you consume. While it is important to eat high-protein foods to fuel your body properly before and after a workout, research has shown that people lose as much muscle on high-protein weight-loss diets as those who follow other types of diets.
A high-protein diet may not prevent muscle loss, but it is still important to consume enough protein to stave off malnutrition and preserve muscle mass and strength as we age. Active people, especially those trying to build muscle mass, may need more protein. For an active adult, about 10% of calories should come from protein. However, some experts suggest that we should be consuming more protein, up to twice the standard recommendations.
On the other hand, some experts claim that the average American diet already contains too much protein, and that there can be risks associated with a very high-protein diet. For example, people who eat a high-protein diet with lots of red meat and saturated fat may have a higher risk of heart disease and colon cancer. Additionally, very high-protein diets have been linked to an increased risk of kidney stones.
To prevent muscle loss while losing weight, it is recommended to combine exercise, particularly resistance and endurance exercises, with a diet higher in protein. This is because exercise stimulates muscle growth, but this process requires an adequate supply of protein. It is also important to note that ethnicity and genetics may play a role in muscle loss, with studies showing that Black people tend to lose more muscle mass in a calorie deficit than White people.
